Minimum radius
Minimum radius
How do you determine the minimum radius required for an 1 1/2 scale locomotive, to determine if a blind drivers would be needed,?...is there a quick and simple formula ?

Re: Minimum radius
As long as you know the lateral movement, axle spacing and number of axles on the rigid frame.it is a simple CAD layout exercise.
Yes..there are formulas but I like to see it (dinosaur)
Remember...blind drivers most often also require wider tires.

Too many things going on to bother listing them.
Re: Minimum radius
Oftentimes, the limiting factor is not the “rigid wheelbase” (the drivers), but the “total wheelbase” (including the leading and trailing trucks), because there is not enough swing in the trucks for a curve. So you should layout a scale drawing of the engine axles and place it on a drawing of the curve, to see what the sideways displacement of the trucks would need to be.

Here are some items. There was a great article in Grand Scales Quarterly Issue 29.

Re: Minimum radius
What is the recommended clearance on each side of the track? Would a 3 foot wide right of way be enough.

Re: Minimum radius
Probably.
Depends on wide some footpegs are mounted....and how overweight the cattle may be.
I have been in many locations that did not have 3 ft on the lift or transfer table...and some fellows have to pull pegs to get in and out

Re: Minimum radius
If you have the space, I'd say more is better. I seem to recall that Quentin once said there should always be enough room for a pregnant woman to disembark.

Re: Minimum radius
A 36 inch ROW only gives 18 inches from the centerline on each side. Pretty easy to snag a tree or bridge member with your knee. 48 inches is much better.

Re: Minimum radius
One idea for ROW is the width of the ballasted track plus one mower width on each side.
